“…Laccases are known to have a broad substrate range and are capable of oxidizing a variety of aromatic compounds, especially phenolic substrates [ 49 ]. Ulčnik et al found that utilizing bacterial laccase was more efficient than using fungal laccase [ 50 ]. Furthermore, the bacterial CotA laccase 3ZDW interacted with endosulfan through strong hydrogen bonds [ 48 ].…”

“…Endosulfan degradation by the bacterial CotA laccase was reported to have happened without the formation of endosulfan sulphate or any other known metabolites, implying full mineralization of endosulfan [ 48 ]. Furthermore, the bacterial laccase CotA from B. subtilis has been shown to have a high capacity for lindane degradation [ 50 ].…”

The use of pesticides and the subsequent accumulation of residues in the soil has become a worldwide problem. Organochlorine (OC) pesticides have spread widely in the environment and caused contamination from past agricultural activities. This article reviews the bioremediation of pesticide compounds in soil using microbial enzymes, including the enzymatic degradation pathway and the recent development of enzyme-mediated bioremediation. Enzyme-mediated bioremediation is divided into phase I and phase II, where the former increases the solubility of pesticide compounds through oxidation–reduction and hydrolysis reactions, while the latter transforms toxic pollutants into less toxic or nontoxic products through conjugation reactions. The identified enzymes that can degrade OC insecticides include dehalogenases, phenol hydroxylase, and laccases. Recent developments to improve enzyme-mediated bioremediation include immobilization, encapsulation, and protein engineering, which ensure its stability, recyclability, handling and storage, and better control of the reaction.

“…Moreover, the function of aromatic compounds degradation [ 56 ] and biological growth promotion [ 57 ] demonstrates its important role in BF biofilms. Intriguingly, OTU25 ( g_Gryllotalpicola ) and OTU33 ( g_Chujaibacter ) in QQBF both responded to exogenous stress and the function of aromatic compounds degradation [ 58 ]. These results suggest that the keystone taxa were not only affected by the degradation of pollutants but were also affected by external factors, such as the addition of Rhodococcus sp.…”

“…The keystone species in BF was identified as f_Microbacteriaceae , which was found a great potential function in aromatic compound degradation and biological growth promotion [ 56 , 57 ]. Meanwhile, the keystone species in QQBF were identified as g_Gryllotalpicola (f_Firmicutes) and g_Chujaibacter , which exhibited the ability to respond to environmental stress, such as maintenance of biofilm stability [ 49 , 50 , 58 ]. These results suggested the possible relationship between microbial community evolution with environmental factors and provide an additional explanation for the presence of higher biomass in BF than that in QQBF.…”

Microbial community regulation and performance enhancement in gas biofilters by interrupting bacterial communication

et al. 2022

Background Controlling excess biomass accumulation and clogging is important for maintaining the performance of gas biofilters and reducing energy consumption. Interruption of bacterial communication (quorum quenching) can modulate gene expression and alter biofilm properties. However, whether the problem of excess biomass accumulation in gas biofilters can be addressed by interrupting bacterial communication remains unknown. Results In this study, parallel laboratory-scale gas biofilters were operated with Rhodococcus sp. BH4 (QQBF) and without Rhodococcus sp. BH4 (BF) to explore the effects of quorum quenching (QQ) bacteria on biomass accumulation and clogging. QQBF showed lower biomass accumulation (109 kg/m3) and superior operational stability (85–96%) than BF (170 kg/m3; 63–92%) at the end of the operation. Compared to BF, the QQBF biofilm had lower adhesion strength and decreased extracellular polymeric substance production, leading to easier detachment of biomass from filler surface into the leachate. Meanwhile, the relative abundance of quorum sensing (QS)-related species was found to decrease from 67 (BF) to 56% (QQBF). The QS function genes were also found a lower relative abundance in QQBF, compared with BF. Moreover, although both biofilters presented aromatic compounds removal performance, the keystone species in QQBF played an important role in maintaining biofilm stability, while the keystone species in BF exhibited great potential for biofilm formation. Finally, the possible influencing mechanism of Rhodococcus sp. BH4 on biofilm adhesion was demonstrated. Overall, the results of this study achieved excess biomass control while maintaining stable biofiltration performance (without interrupting operation) and greatly promoted the use of QQ technology in bioreactors.

“…Chujaibacter soli is essential in polyfluoroalkyl substances and lindane degradation, while Arthrobacter sp. can degrade unusual and polymeric compounds ( Senevirathna et al, 2022 ; Wu et al, 2022 ). Both bacteria play a crucial role in biodegrading agrochemicals and pollutants but were suppressed by M. incognita in rhizosphere soils.…”

Microbial landscapes of the rhizosphere soils and roots of Luffa cylindrica plant associated with Meloidogyne incognita

IntroductionThe root-knot nematodes (RKN), especially Meloidogyne spp., are globally emerging harmful animals for many agricultural crops.MethodsTo explore microbial agents for biological control of these nematodes, the microbial communities of the rhizosphere soils and roots of sponge gourd (Luffa cylindrica) infected and non-infected by M. incognita nematodes, were investigated using culture-dependent and -independent methods.ResultsThirty-two culturable bacterial and eight fungal species, along with 10,561 bacterial and 2,427 fungal operational taxonomic units (OTUs), were identified. Nine culturable bacterial species, 955 bacterial and 701 fungal OTUs were shared in both four groups. More culturable bacterial and fungal isolates were detected from the uninfected soils and roots than from the infected soils and roots (except no fungi detected from the uninfected roots), and among all samples, nine bacterial species (Arthrobacter sp., Bacillus sp., Burkholderia ambifaria, Enterobacteriaceae sp., Fictibacillus barbaricus, Microbacterium sp., Micrococcaceae sp., Rhizobiaceae sp., and Serratia sp.) were shared, with Arthrobacter sp. and Bacillus sp. being dominant. Pseudomonas nitroreducens was exclusively present in the infested soils, while Mammaliicoccus sciuri, Microbacterium azadirachtae, and Priestia sp., together with Mucor irregularis, Penicillium sp., P. commune, and Sordariomycetes sp. were found only in the uninfected soils. Cupriavidus metallidurans, Gordonia sp., Streptomyces viridobrunneus, and Terribacillus sp. were only in the uninfected roots while Aspergillus sp. only in infected roots. After M. incognita infestation, 319 bacterial OTUs (such as Chryseobacterium) and 171 fungal OTUs (such as Spizellomyces) were increased in rhizosphere soils, while 181 bacterial OTUs (such as Pasteuria) and 166 fungal OTUs (such as Exophiala) rose their abundance in plant roots. Meanwhile, much more decreased bacterial or fungal OTUs were identified from rhizosphere soils rather than from plant roots, exhibiting the protective effects of host plant on endophytes. Among the detected bacterial isolates, Streptomyces sp. TR27 was discovered to exhibit nematocidal activity, and B. amyloliquefaciens, Bacillus sp. P35, and M. azadirachtae to show repellent potentials for the second stage M. incognita juveniles, which can be used to develop RKN bio-control agents.DiscussionThese findings provided insights into the interactions among root-knot nematodes, host plants, and microorganisms, which will inspire explorations of novel nematicides.
